我是MVC和AngularJs的新手。我的问题是-我正在使用ng-重复显示数据。调试显示,javascript和MVC控制器中的数据检索都是正确的。即使是ng-重复也能正常工作,但是所有的行都是在没有任何数据的情况下生成的。我的意思是生成12行空白。下面是Json的数据。
{"categoryID":1,“categoryName”:“饮料”,“描述”:“软饮料、咖啡、茶、啤酒和啤酒”}、{"categoryID":2、“categoryName”:“调味品”、“描述”:“甜味调味汁、调味品、调料”}、{"categoryID":3、“categoryName”:“categoryName”、“描述”:“Desserts、糖果和甜面包”},{"categoryID":4,“categoryName”:“奶制品”,“描述”:“奶酪”},{"categoryID":5,“categoryName”:“谷物/谷物”,“描述”:“面包、饼干、意大利面和谷物”},{"categoryID":6,“categoryName”:“肉类/家禽”,“描述”:“准备好的肉类”},{"categoryID":7,“categoryName”:“农产品”,“描述”:“干水果和豆腐”},{"categoryID":8,“categoryName”:“海鲜”,“描述”:“海草和鱼类”} {"categoryID":9,"categoryName":"www",“categoryName”},{“ghhhh”},{"categoryID":10,"categoryName":"bbb",“描述”:“nnn”},{"categoryID":11,"categoryName":"asd",“asd”:“sdsad”},{"categoryID":12,"categoryName":"ssfsf",“描述”:“af1”}
这是我的控制器(CategoryController.cs)
 public ActionResult GetCategory()
        {
            var categoryList = from cat in _db.Categories
                select new
                    {
                        cat.CategoryID,
                        cat.CategoryName,
                        cat.Description
                    };
            return Json(categoryList, JsonRequestBehavior.AllowGet);
        }我的app.js文件
var myApp = angular.module('myApp', ['ngRoute', 'ngResource', 'ui.bootstrap']);我的Router.js文件
myApp.config(['$routeProvider', function ($routeProvider) {
    $routeProvider.when('/', {
        templateUrl: "App/Home/home.html"
    }),
    $routeProvider.when('/about', {
        templateUrl: "App/Home/about.html"
    }),
    $routeProvider.when('/category', {
        templateUrl: "App/Category/Html/categoryList.html",
        controller: "categoryController"
    });
}]);我的categoryController.js文件
myApp.controller('categoryController',
    ['$scope', 'categoryDataService', '$location',
    function categoryController($scope, categoryDataService) {
        $scope.categories = [];
        loadCategoryData();
        function loadCategoryData() {
            categoryDataService.getCategories()
            .then(function () {
                $scope.categories = categoryDataService.categories;
            },
                function () {
                    alert("Error");
                })
                .then(function () {
                    $scope.isBusy = false;
                });
        };
    }]);我的categoryDataService.js文件
myApp.factory('categoryDataService', ['$http', '$q',
function ($http, $q) {
    var _categories = [];
var _getCategories = function() {
    var deferred = $q.defer();
    var controllerQuery = "Category/GetCategory";
    $http.get(controllerQuery)
        .then(function(result) {
                // Successful
            angular.copy(result.data, _categories);
                deferred.resolve();
            },
            function(error) {
                // Error
                deferred.reject();
            });
    return deferred.promise;
};
//Expose methods and fields through revealing pattern
return {
    categories: _categories,
    getCategories: _getCategories
}
}]);我的CategoryList.html文件。

如果您能够生成您的行,并且按您所说的那样正确地请求数据,那么我相信您正面临一个问题,原因是您的角度数据库中的表达式如下:
{{category.CategoryName}}
代之以
{{category.categoryName}}
并对json对象的每个属性重复此操作。
